What to do
Operators must amend the Aircraft Flight Manual within 7 days after 26 February 2025 to include procedures from Airbus Operations Engineering Bulletin 58 issue 1.0 and inform flight crews accordingly. Concurrently, the Master Minimum Equipment List must be updated as per the Airbus A330/A340 MMEL Major Event Revision dated 10 February 2025. Continued operation must follow these updated procedures and MEL requirements.
Summary
EASA Airworthiness Directive 2025-0043R1 is an amendment addressing Airbus A330-243, A330-243F, A330-841, and A330-941 aeroplanes equipped with Airbus modification 207423 but not modification 211442. The directive mandates updates to the Aircraft Flight Manual and Master Minimum Equipment List to mitigate issues related to loss of data synchronization between Radio Management Panels and the Audio Management Unit. This AD aims to prevent loss of radio communication control, transponder and TCAS setting changes, and standby navigation activation.
What changed
This revision reduces the applicability of the original AD 2025-0043 by exempting aeroplanes with Airbus modification 211442 installed, which addresses the unsafe condition. It also corrects the applicability section and reaffirms that the AD remains an interim action pending further directives. The amendment requires operators to implement updated procedures and MMEL changes as per Airbus documentation.
Why it matters
This AD is critical for operators and maintenance organizations to ensure continued safe operation of affected Airbus A330 models by preventing communication and navigation system failures. Compliance helps avoid potential total loss of radio communication and transponder functionality, which are essential for flight safety and regulatory adherence. It also clarifies exemption criteria, reducing unnecessary compliance burden on unaffected aircraft.
